There are 2 sorts of bad sectors: logical and physical. While logical bad sectors are simply fixed using particular software, physical bad sectors can be irreparable. But it does not mean there’s no hope, there’s still an opportunity to recover the bad sectors dependent on how “deep” the bad sectors are. So, below I’m going to consider only physical bad sectors, their symptoms, reasons for appearing, types and methods for possible upkeep. There are principally 2 symptoms you can come across with:
- Blue screen of death appears regularly showing the mistake code meaning that a memory read attempt failed. It follows with inevitable restarting and the following blue screen follows pretty shortly with similar blunder code again. The same message is displayed when there’s a difficulty with DDR memory. But memory modules are simply replaced, or perhaps fixed by replacing the bad chip.
- Operating system doesn’t boot with a message showing that some system files can not be found.
One of the explanations for bad sectors is that some areas of HDD, which are most frequently used, “wear out” and become harder to read and eventually, utterly untouched. Though it is feasible to “recover” these sectors using some applications, it’s way better to get a new HDD for use as the main system drive and the corrected one use for other reasons. The reason is that although the bad sector is fixed, all of your info is safe and the HDD is working again, there’s a risk the prior or the following sectors are also about to collapse shortly. Using for extra storage purposes isn’t the worst choice for such drive. One more reason for physical bad sectors is a shock, which exceeds the satisfactory boundaries, particularly, inflicted while the HDD is operating.
In this situation numerous bad sectors are nearly inevitable. Sometimes, after such an accident HDD comes to a completely worthless condition, when it’ll keep making a particular sound attempting to start spinning, but will not. Imagine a disk revolving with the speed of over 5000 revs per minute.
Is it feasible to make a single dot on it by touching it with, let’s imagine a pencil? The answer’s “No”. It is completely most unlikely to avoid a pleasant clear circle rather than a dot. For an HDD such a circle means a big area of storage, which is untouched. These days, the HDD have average size of 5 hundred GB and the price ranges around $70. This is a reasonable price, but the info contained in HDD could be dearer. So, such issues as shown above need some solutions, and positively with good results.
As I discussed, depending on the situation you are you may use software, which in most situations are beneficial. These categories of applications may be able to access the drive in any case the file system and recover the information and even the bad sectors. If you aren’t sure or it appears the HDD is totally dead, possibly, it’s better to have the task finished by a pro.
